Dear Maintainer,

faketime and libfaketime in and after Debian 11 (bullseye) do not fake
timestamps to common commands which use the statx syscall, such as
stat(1) or ls(1). Instead, the on-disk timestamps are returned:

  # LD_PRELOAD=/usr/lib/x86_64-linux-gnu/faketime/libfaketime.so.1 FAKETIME='1970-01-01 00:00:01' stat /
    File: /
    Size: 4096 Blocks: 8 IO Block: 4096 directory
  Device: 72h/114d Inode: 14475976 Links: 1
  Access: (0755/drwxr-xr-x) Uid: ( 0/ root) Gid: ( 0/ root)
  Access: 2024-02-13 00:08:45.027068497 +0000
  Modify: 2024-02-13 00:08:45.027068497 +0000
  Change: 2024-02-13 00:09:55.450105641 +0000
  Birth: 2024-02-13 00:08:45.027068497 +0000

In Debian 10 (buster) and earlier, or in sid with faketime built from
the current git master branch, the correct result is returned (all
timestamps are returned as 1970-01-01 00:00:01.0). This seems to be
related to upstream bug https://github.com/wolfcw/libfaketime/issues/417
which was fixed by PR https://github.com/wolfcw/libfaketime/pull/434

Unfortunately, faketime hasn't had a release since that fix for statx
was merged.

Control: forwarded -1 https://github.com/wolfcw/libfaketime/issues/417
Control: tags -1 patch
Lets tag it like that.

Hi.

I am preparing an upload for faketime to fix the 32-bit failures.  I
saw this bug and thought I would try to include this fix.

I used `git-cherry-pick 942b30e9400d50cc95b19b7fb3d81c2def1f984a`
to collect the commit from upstream MR !434.  But in my tests, it
didn't work:

$ LD_PRELOAD=/usr/lib/x86_64-linux-gnu/faketime/libfaketime.so.1 FAKETIME='1970-01-01 00:00:01' stat /
  File: /
  Size: 4096            Blocks: 8          IO Block: 4096   directory
Device: 253,1   Inode: 2           Links: 21

I don't know why this is but perhaps there's a statx64 or something?
I haven't investigated further.

One approach I didn't investigate was to try upstream unreleased
mainline.  If we did that we'd probably want to review quite carefully
what we were shipping.  I don't think this is suitable for the NMU I
am now preparing.

Anyway, thanks for the contribution, and sorry not to be including
this fix.

Ian.
